Observation and analysis of creation, decay, and regeneration of annular soliton clusters in a lossy cubic-quintic optical medium
Albert S. Reyna, Henrique T. M. C. M. Baltar, Emeric Bergmann +5
We observe and analyze formation, decay, and subsequent regeneration of ring-shaped clusters of (2+1)-dimensional spatial solitons (filaments) in a medium with the cubic-quintic (f…

Optical vortices: the concept of topological potential and analogies with two-dimensional electrostatics
Anderson M. Amaral, Edilson L. Falcão-Filho, Cid B. de Araújo
We show how the phase profile of a distribution of topological charges (TC) of an optical vortex (OV) can be described by a potential analogous to the Coulomb's potential for a dis…
